Donkey Kong Country is a blast!
You can either play as Donkey Kong, or his nephew Diddy who is new to the game. You can gain the help of 5 animals by breaking certain crates. The animals are Rambi the Rhino, Expresso the Ostrich,, Enguarde the Swordfish,
Winky the Frog, and Squawks the Parrot. Some animals are only found in certain levels like Enguarde is only found underwater and Squawks will be found in caves.
What really shines in this game is the music. If you want a game with a stellar soundtrack Donkey Kong Country is definitely a must own for you. My favourite track is the final boss theme.
So if you own a SNES you should give Donkey Kong Country a try.
